‘Morning people’ have lower breast cancer risk

Women whose body clocks mean they are "morning people" have a lower risk of developing breast cancer, say UK researchers.
The team at the University of Bristol says the reason why still needs to be uncovered.
It adds the findings are important as they may affect every woman's risk.
Experts said the study presented at the NCRI Cancer Conference in Glasgow added to a growing understanding of the importance of sleep in all health.
